Let php process images easily. For more information, see. The design idea of this class draws on jQuery and uses the concatenation method to operate images, such:
The code is as follows:
$ Image = new UsaImage (array ('filepath' => 'image1.jpg '));// The Image overwrites an image. parameters 2 and 3 are the x and y positions to be placed.$ Image-> Overlap ("image99.gif", 10, 10)// Overwrite the image
(); if (response! = NULL) response. Close ();}As for how to find the image URL skip, just say download Picture itIn fact, the same as above, there are two ways:1,webrequest and WebResponseWebRequest request = WebRequest.Create ("Http://images.cnblogs.com/logo_small.gif"); WebResponse response = Request. GetResponse (); Stream reader = response. GetResponseStream (); FileStream writer = new FileStream ("X:\\pic.jpg", FileMode.OpenOrCreate, F
We often need to download a lot of favorite pictures on the page, but facing dozens of or even hundreds of pictures, one to save as a must be a bad experience.We can use the Urllib package to obtain the HTML source code, and then the regular expression to the matching image link into a list, using a for loop to download the list of links in sequence.ImportReImportUrlliba= Raw_input ("Please input a URL:") s
To obtain the image of the img tag on the UIWebView page, you can obtain the URL and download it again. The image consumes traffic, time, and cannot pass verification. Here we use the stringByEvaluatingJavaScriptFromString function of UIWebView to execute a javascript code and return the image to be obtained from the img tag on the UIWebView page. The method on the Internet is to obtain the URL and download
Recently, I am working on a function to save it as an image.
In fact, this function is quite simple. You can use todataurl () conversion, or directly use the canvas2image. js and base64.js scripts to implement the function,
Some important code is as follows:
// Use JavaScript code to download var imagedate = document. getelementbyid ("canvas "). todataurl ("image/PNG"); window. location. href = "image/octet-stream" + imagedate; // search for these

First, if you want to implement a transparent background image, it can be a png image or a gif image. However, when you use a gif image, there will be a significant sawtooth effect, in IE6, the background of a transparent PNG image changes to gray (# DBEAED), which can only blame the poor rendering of IE engine.

In the previous section, we used handler, thread/runnable, URL, httpurlconnection, and so on to asynchronously download network images.
However, using this method has the following Disadvantages:
The thread overhead is large. If each task needs to create a threadProgramEfficiency is much lower.
Threads cannot be managed. Anonymous threads are not controlled by the program after they are created and st
Use LruCache and DiskLruCache to download images,
LruCache is a good image caching tool:
The main method is to cache the bitmap of the image in LruCache
Therefore, we must set an image cache address:
public void setImageCache(){ String strPath = null; if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) { File sdFile = Environment.getExternalStorageDirectory(); strPath

SpringMVC + ajaxFileUpload solution for uploading images to IE browser via pop-up download box
For example, record the solution to this problem. The core cause is that ajaxfileupload does not support setting the Response Header ContentType to application/json, and IE does not support this format, when SpringMVC's @ ResponseBody annotation is used, the response type is automatically set to application/json
